MAX1730x/MAX1731x Battery Pack Implementation Guide

Abstract: This application note describes the various steps for implementing MAX17301-MAX17303/MAX17311-MAX17313 1-Cell ModelGauge m5 EZ Fuel Gauge with Protector and SHA-256 Authentication in a battery pack. Please follow the guide closely during design, evaluation and production phases. System circuit design and layout that doesn’t follow guidance may affect measurement accuracy. The memory programming instructions describe how to load the fuel gauge and authentication information and lock it to prevent tampering with the authentication or fuel gauge mechanisms. Please see Software Implementation Guide for details on software implementation.
